To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
The first step when finding an HCF is to break the numbers down into their prime factors. In this case we get: 21 = 3x7 49 = 7x7 The next step is to identify any common prime factors. In this case both numbers have a 7 as a prime factor. There are no more common prime factors, and thus the HCF of 21 and 49 is 7.
The least common multiple of the numbers 21, 48 and 49 is 2,352.
The factors of 147 are 1, 3, 7, 21, 49, and 147.
The factors of 147 are 1, 3, 7, 21, 49, and 147.
Factors or 21 are: 1 3 7 21 Factors or 49 are: 1 7 49 Common factors of 21 and 49 are: 1 and 7
Do you mean, what are the common factors of 49, 21, and 91? Only 7 (and 1, of course) is a common factor for those numbers. Individually, 49's factors are 1, 7 and itself. 21's factors are 1, 3, 7, and itself. 91's factors are 1, 7, 13, and itself.
Factors of 21 are 3 and 7 (21=3x7). Factors of 35 are 5 and 7 (35=5x7). Factors of 49 are 7 and 7 (49=7x7).
The factors of 21 are 1, 3, 7, 21 The factors of 49 are 1, 7, 49 The largest matching number is 7 so 7 is the GCF of 21 and 49.
the factors of 21 are 3,7,1, 21,and -1, -21,-3,-7. the factors of 49 are 1,49,7,7 and -1, -21-7-7.
All Factors of 147:1, 3, 7, 21, 49, 147
The first step when finding an HCF is to break the numbers down into their prime factors. In this case we get: 21 = 3x7 49 = 7x7 The next step is to identify any common prime factors. In this case both numbers have a 7 as a prime factor. There are no more common prime factors, and thus the HCF of 21 and 49 is 7.
1,7, and 49 are the factors of 49Factors are numbers that can be divided from a certain number. Factors of 49 can be worked out by multiplying different numbers with another number.1, 7, and 49.
The factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are:1, 7
No, the only factors of 49 are 1, 7, and 49. Therefore, 8 and 5 are not factors of 49.
To find the greatest common factor (GCF) of 21, 49, and 63, we first need to find the prime factorization of each number. The prime factorization of 21 is 3 x 7, 49 is 7 x 7, and 63 is 3 x 3 x 7. The GCF is the product of the common prime factors raised to the lowest power they appear in all the numbers, which in this case is 7. Therefore, the GCF of 21, 49, and 63 is 7.
